FIG. 1 depicts an embodiment of features of a method to provide routing by a virtual bridge. At 110, an address of a frame is established as being associated with a physical device or a virtual device. At 120, if the frame is associated with a virtual device, the address of the frame is established as being associated with a local virtual device or a remote virtual device. A local virtual device resides on the virtual platform associated with the virtual bridge and a remote virtual device resides on another virtual platform. In an embodiment, a method includes establishing an address of a frame as being associated with a virtual device by generating an address that identifies within the address that the address is associated with a virtual device. In an embodiment, a method includes assigning a portion of the address of the frame a value such that the value is different from those assigned to physical devices. In an embodiment, such a virtual device may be a virtual network interface. The virtual network interface may be realized as a virtual network interface card. In an embodiment, a method includes establishing an address of a frame as being associated with a physical device or a virtual device by checking information in an address for a frame that identifies within the address whether the frame is to be routed to a real device or a virtual device. In an embodiment, a method includes routing the frame based on checking information in an address to determine whether to route the frame to a specific local virtual device or a remote virtual device. In an embodiment, such a virtual device may be a virtual network interface card. - An embodiment provides an approach to create a scalable and high-performance virtual bridge in a virtualized platform. An apparatus having virtual machines (VMs) permits the apparatus, a real (physical) machine, to be partitioned, such that the underlying hardware of the apparatus appears as one or more independently operating physical machines. Each VM may function as a self-contained platform, running its own operating system (OS) and/or application software. Software executing within a VM is collectively referred to as guest software. A Virtual Machine Monitor (VMM) runs on an apparatus that executes instructions and presents to other software an abstraction of one or more VMs. The VMM may be in control of the platform. The VMs, running guest OSs, are isolated replicas of the hardware that are managed by the VMM. The VMM may provide a management application that allows the end user or administrator to set the number of VMs to launch and assign to a VM zero, one, or multiple virtual network interface cards (VNICs). Similar to real network interface cards, each VNIC has an address associated with it. The address may include a medium access control (MAC) address.

FIG. 2 depicts an embodiment of anapparatus 200 having hardware 210 and avirtual machine monitor 220, VMM 220, to control a virtualized platform. Hardware 210 may include a computing platform capable of executing an operating system (OS) and VMM 220. Hardware 210 may include one ormore processors 212 andmemories 214.Processor 212 can be any type of processor capable of executing software, such as a microprocessor, digital signal processor, microcontroller, or the like. Theprocessor 212 may include microcode, macrocode, software, programmable logic or hard coded logic for performing the execution of various embodiments.Memory 214 can be a hard disk, a floppy disk, random access memory (RAM), read only memory (ROM), flash memory, any other type of machine medium readable byprocessor 212, or any other processing device inapparatus 200.Memory 214 may store instructions and/or data for performing the execution of various embodiments to provide routing by avirtual bridge 230. Hardware 210 may include a number of devices not shown inFIG. 2 , such as input/output devices. Such other devices are omitted to focus on various embodiments. Hardware 210 may include a personal computer (PC), mainframe, handheld device, portable computer, set-top box, intelligent appliance, or any other computing device or system. - VMM 220 includes
virtual bridge 230, which enforces the virtual network configuration set by a user. Routing complexity that may arise typically resides invirtual bridge 230, which is a component for multiplexing outbound traffic and demultiplexing inbound traffic. The multiplexer side is responsible for determining whether outgoing frames should be looped back to another virtual device within the system, sent out to the real network, or both. The demultiplexer side decides to which virtual device incoming frames should be routed. In general, a bridge incurs up to n times the complexity when making its MAC level routing decisions, where n is the number of MAC addresses stored in the bridge's memory. In various embodiments, means are provided forvirtual bridge 230 to reduce its time complexity to the order associated with one MAC address. - In a non-limiting exemplary embodiment,
FIG. 2 shows virtual machines 240-1, 240-2 under the control of VMM 220, where VMM 220 includes virtual network interface cards (VNICs) labeled VNIC1 250-1, VNIC2 250-2, VNIC3 250-3. As can be appreciated by those skilled in the art,apparatus 200 is not limited to two VMs, but may include any number of VMs. Further, VMM 220 is not limited to three VNICs, but may include any number of VNICs. Hardware 210 for VMM 220 includes a network interface card (NIC) 260, which is a physical (real) NIC. Each of the VNICs 250-1, 250-2, 250-3 is associated with NIC 260. Virtual machines 240-1, 240-2 and VNIC1 250-1, VNIC2 250-2, VNIC3 250-3 are local virtual devices associated with real NIC 260. Remote virtual machines and remote virtual NICs may be associated with another real network interface card. - A straight-forward approach for
virtual bridge 230 to make its routing decisions is to store all VNIC MAC addresses in a list, either statically or dynamically allocated, and, for every outgoing/incoming frame, perform a sequential search through every VNIC of every VM. However, this scheme does not scale well as the number of VMs and/or VNICs per VM grows. In an embodiment, a unique scheme is provided to assign MAC addresses to the VNICs so thatvirtual bridge 230 may make a routing decision with a single access to a routing table. In an embodiment, a portion of an address of a frame is assigned a value such that the value is distinguished from those assigned to physical devices. In such a case, the value indicates that the address is for a virtual device such that no physical device is associated with the assigned value. To further identify a virtual device, creation or generation of the address may include assigning an index to another byte of the address, where the index belongs to a table that maintains pointers to virtual device objects. However, since virtual devices may be associated with different physical devices at various locations in a network or networks, the address of the given virtual device is assigned a number of bytes that are a part of the physical device to which the virtual device is associated. - In an embodiment, a 6-byte MAC address is created for a VNIC, where the first byte is set to a value that is different from the first byte of all the assigned Organizationally Unique Identifiers (OUIs). An OUI is a 24-bit globally unique assigned number referenced by various standards. The 24-bit structure for an OUI may change as variations in technology occur. By examining an OUI, a determination can be made as to the manufacturer of the physical NIC. In an embodiment, the first byte for the VNIC could be set to 0x0D, since it is reserved and no vendor OUI starts with this value. Because no vendor has a product OUI that starts with 0x0D, an address starting with 0x0D identifies a VNIC rather than a real NIC. By selecting a unique OUI prefix, collisions with real MAC addresses are eliminated. In an embodiment, depending on the standard used, the value that identifies the address as belonging to a virtual device may be located in another portion of the MAC address other than the first byte.
- In an embodiment, the second byte may be an index of a table that maintains pointers to all VNIC objects. Depending on the standard, the index of the table may be located in another portion of the MAC address. The table effectively maps the MAC address to a data structure that contains VNIC specific information such as callback routines, DMA pointers, registers, etc. VNIC objects provide data structures to interface with the VMM. These VNIC objects may be data structures providing parameters that associate VNICs to VMs and are used by the VMM to route a packet to a VM.
-
FIG. 3 illustrates an embodiment of a table 300 associated with VNIC1 250-1, VNIC2 250-2, and VNIC3 250-3 ofFIG. 2 managed byVMM 220, where these VNICs haverespective indexes - The index may be randomly generated. In an embodiment, when an apparatus or a system is started or powered up, part of the VMM initialization may include creating VNIC objects. Generation of the VNIC objects may be managed by the VMM as part of the creation of VNICs including the assignment of a MAC address to each VNIC. At the beginning of the process, the table may be empty and as VNICs are created, an entry is assigned in the table. The manner in which the index is assigned may vary, as long as only one index is assigned to each VNIC. Thus, as the apparatus proceeds through the initialization process, a VNIC is created, a data structure for the VNIC is created, and a MAC address is generated for the VNIC with the MAC address including the index. Then, the process continues for each additional VNIC including providing a table index. The table index may be any index in the table as long as it is unique to the VNIC being created. In an embodiment, the indexes may be assigned sequentially as the VNICs are generated. There are no restrictions to assigning the index as long as the index assignments are unique.
- In an embodiment, the last four bytes of the address of a VNIC are assigned the last four bytes of the address of the physical NIC that provides routing of frames to the VNIC from a location external to its VMM. The routing external to the VMM is exemplarily shown in
FIG. 2 by the arrows fromNIC 260 tovirtual bridge 230. Depending on the standard, the assignment of address information tying the VNIC to its associated physical NIC may use more or less bytes and be located in another portion of the MAC address. -
FIG. 4 illustrates an embodiment of the components of aMAC address 400 of a VNIC, which may be generated by a VMM, for example,VMM 220 ofFIG. 2 . As shown inFIG. 4 , MAC address includes aprefix byte 410 from a reserved pool, atable index 420 that is randomly generated, andreal bytes 430 that are the lower four bytes of the real NIC's address. The length of the routing table index, for example table 300 ofFIG. 3 , and the remaining fields in the VNIC MAC address can be adjusted according to the maximum number of VNICs supported by an apparatus or system. For example, the MAC address format shown inFIG. 4 supports up to 256 virtual MAC addresses. Increasing the table index field length to two bytes (and reducing the real NIC's suffix to three) provides entries for up to 65000 VNICs. - In various embodiments of methods that provide a scheme for routing by a virtual bridge, a routing table may be used that embeds an index to the routing table in the VNIC's MAC address to preclude the need for a sequential search to route frames. A reserved prefix may be used in the MAC address to eliminate collisions with the MAC addresses of real NICs. Random values and a subset of a real NIC's MAC address may be used to minimize collisions among VNICs' MAC addresses. In various embodiments, MAC addresses are created for VNICs during apparatus boot up as part of the process of creating a VNIC and MAC addresses by the VMM. Then, VMs may interact with their associated VNICS including obtaining the MAC address of their associated VNICS. With a MAC address having a format in accordance with embodiments discussed herein, the virtual bridge may operate at enhanced speed.
- Embodiments for a MAC address for a virtual device may be used by a virtual bridge, such as
virtual bridge 230 ofFIG. 2 , to route frames to appropriate VMs. An embodiment of a method is shown inFIG. 5 . At 510, a check is made to determine whether a set of information in the address of the frame is associated with a physical device or a virtual device. At 520, a check is made to determine whether another set of information in the address is associated with an address of a local physical device or a remote physical device associated with the virtual device. A routing table may be accessed at an index specified by a third set of information in the address. After accessing the routing table, the frame may be forwarded to the appropriate local virtual network interface card. - In an embodiment, when a frame reaches a virtual bridge, such as
virtual bridge 230 ofFIG. 2 , the virtual bridge determines whether the destination MAC address is real or virtual by checking the first byte. If the destination is real, the frame is passed down to the physical NIC to be sent out to the external network (external to the physical NIC and the virtual bridge). If the destination NIC is virtual, the bridge further checks the last four bytes to determine if the VNIC is local or remote. If the destination is remote, the frame is also passed down to the physical NIC to be sent out to the external network. If the destination is local, a routing table is accessed at the index specified by the second byte of the MAC address. The virtual bridge may then forward the frame with respect to the appropriate VNIC according to the table entry. The remaining hand shaking with respect to sending information to a VM may be managed the VMM. In an embodiment, for a configuration in which each VNIC is associated with one VM, by checking the frame to select an appropriate VNIC, the virtual bridge makes a decision to route information to a particular VM by selecting the VNIC for routing. A VM may be operatively coupled to multiple VNICs. - Embodiments, such as those described herein, may increase the routing performance of the virtual bridge significantly by reducing routing time complexity from on the order of n to about the
order 1 VNIC with a marginal increase in the memory. For example, a 1 KB table may be used to handle 256 VNICs. The virtual bridge may handle any number of VNICs with no change in the routing performance, providing scalability. Various embodiments may also provide elimination of collisions among MAC addresses of VNICs in the same virtual system, elimination of collisions among virtual MAC addresses and real MAC addresses, and reduced chance of collision among MAC addresses of VNICs that reside in different systems. Various embodiments providing such dynamic routing by a virtual bridge may enhance virtualization solutions for various applications. -
FIG. 6 illustrates a block diagram of an embodiment of asystem 600 that includes a virtualized platform in which a virtual machine monitor, realized in various embodiments including that shown inFIG. 2 , has a virtual bridge to route frames to and from virtual machines using an address having information that identifies the frame as being associated with a virtual device rather than a real device.System 600 includes acontroller 610, amemory 620, and a bus 630, where bus 630 provides electrical connectivity betweencontroller 610 andmemory 620. Bus 630 may be a parallel bus. Alternatively,system 600 may includecontroller 610 coupled tomemory 620 via a serial bus to execute instructions for a virtualized platform. In an embodiment,controller 610 is a processor, such asprocessor 212 ofFIG. 2 .Memory 620 may include any form of computer-readable medium that has computer executable instructions to establish an address of a frame as being associated with a physical device or a virtual device, and, if the frame is associated with a virtual device, to establish the address of the frame as being associated with a local virtual device or a remote virtual device, to provide routing by a virtual bridge. - An embodiment may include an additional peripheral device or
devices 660 coupled to bus 630. Bus 630 may be compatible with PCI or with PCI express.Peripheral devices 660 may also include displays, additional storage memory, or other control devices that may operate in conjunction withcontroller 610. Alternatively,peripheral devices 660 may include displays, additional storage memory, or other control devices that may operate in conjunction withcontroller 610 and/ormemory 620. -
System 600 may include acommunication unit 640 coupled tocontroller 610 via parallel bus 630. In an embodiment,communication unit 640 may include a network interface. In an embodiment, the network interface may be implemented in a semiconductor device (i.e., a “chip”). Alternatively, in various embodiments, the network interface may be integrated in separate semiconductor devices forming part of a family of chips called a “chip set.” A chip set may be realized as a group of microchips designed to work and to be sold as a unit in performing one or more related functions. In an embodiment,communication unit 640 may include a network interface implemented as a network interface card, such asNIC 260 ofFIG. 2 .Communication unit 640 may provide a means for a VM ofsystem 600 to communicate and interact with a VM of another system, in which virtual bridges in these systems may route information using various embodiments according to the teachings described herein. Each VM ofsystem 600 may be associated with one or more virtual network interfaces. Such systems may be on a local area network or wide area network. In addition, VMs on different systems may be configured as part of a network virtualization. Using embodiments for generating MAC addresses and checking MAC addresses, information may be routed through a network from one system to another system using standard routing protocols.System 600 may include, but is not limited to, information handling devices, wireless systems, telecommunication systems, fiber optic systems, electro-optic systems, and computers, where each system may operate a virtualized platform. - Various embodiments for methods and apparatus allow for increased speed of operation to make a routing decision using a virtual bridge. In an embodiment, information in an address may be used to distinguish between a real device and a virtual device. Other information in the address may be used to index directly into a table to distinguish between different virtual devices on the same virtual platform. Other information may be used to associate the virtual device with a given real device, which indicates whether the virtual device is local or remote to the apparatus or system having the virtual platform.
